Title: Equivolumetric pump for continuous electrophoresis process appts - has pistons with common adjustable drive linkage
Inventor: STEPANEK JIRI
IPC: F04B49/12
Filed: 1975-02-18
Abstract: The multi piston pump is used for very accurate, simultaneous metering of given samples into the working gap of an electrophoresis apparatus. The piston pump has a number of parallel connected cylinders made from syringe glass tubes. Pistons have electrically insulating collars which prevent entry of the pumped liquid into the driving mechanism. These pistons are driven in parallel by the pivoted rods which are connected by sockets to a common rod connected to a single arm lever which pivots about a pin. The single arm is connected by an adjustable length rod with locking device to the drive. Manual operation is used for removing bubbles. The flow is more uniform than that achieved with a peristaltic pump.
Patent DE-2508969-A1 (DE)
Inventor: REHR WINFRIED DR ING
IPC: B65H63/06
Filed: 1975-03-01
Abstract: The monitoring device is intended to be insensitive to disturbances and not respond to nib-thick places. Each operating point has a sensor (12) for monitoring the yarn cross-section with analogue signal output. The analogue signals (13) are converted into digital signals (15) and compared with set values. In cases of deviations from the set value, the yarn is separated and the operating point concerned is shut down. The interrogating of the individual operating points can take place in rapid succession one after the other from a central point (17). With a very rapid interrogating cycle, sum values can be formed thereby for every individual operating point and compared with sum set values. As a result, thick places and thin places are detected at a very early time, because to a certain extent the principle involved is that of monitoring the yarn volume. There is expediently a digital measured-value processing system (17) for each textile machine. <IMAGE>

Title: Impact resistant glass incorporating asymmetric laminates - for light weight with progressive resistance to penetration
Inventor: BREITENBUERGER GERTRUD
IPC: C03C27/12
Filed: 1975-09-24
Abstract: Impact resistant glazing comprises one solid sheet of glass as an external pure 6-20 mm thick separated by a n air gap from an internal pane which is composite, asymmetric sheet >=5 mm thick of layers of glass of diminishing thickness separated by intermediate layers of plastic film, of which at least the film nearest the interior of the buildings is >1 mm thick. Suitable for bullet proof or shrapnel resistant glazing for shop windows, limousines, etc. The surface layers are more scratch- and sunlight-resistant than glazing made of transparent plastics. The progressively increasing flexibility of the constituent layers of the internal pane give successive energy loss from impinging objects penetrating the structure, to provide a much higher impact resistance/weight ratio than solid glazing which offers the same impact resistance.
